Ralph Filmore is just your average, everyday, 12 year old Paranormal Investigator. He hunts down and challenges all things strange and bizarre on a daily basis despite being the shortest kid in 7th grade, getting picked on by bullies, and still having to be in bed by 9PM. Ralph's serious obsession for paranormal phenomena gets him into heaps of trouble, but with his best friend/partner in slime, Booker, his trusty robotic supercomputer, Z and his ghostly canine companion, Specter, Ralph protects the people of Earth from extraterrestrial and supernatural threats.
